xturing 为 LLM 提供了快速、高效和简单的微调，如 LLaMA、GPT-J、GPT-2、OPT、Cerebras-GPT、Galactica 等。通过提供一个易于使用的界面，再根据你自己的数据和应用来个性化 LLM，xTuring 使构建和控制 LLM 变得简单。整个过程可以在你的电脑内或在你的私有云中完成，确保数据的隐私和安全。
通过 xturing，你可以：
- 从不同的来源摄取数据，并将其预处理成 LLM 可以理解的格式
- 从单个 GPU 扩展到多个 GPU，以便更快地进行微调
- 利用内存效率高的技术（即 LoRA 微调）来减少你的硬件成本，最多可减少 90% 的时间。
- 探索不同的微调方法，并以它们为基准，找到性能最好的模型
- 在明确定义的指标上评估微调模型，进行深入分析
